As part of an ETV test of slurry additive Active NS, FORCE Technology undertook measurements of ammonia during two periods in 2016 and 2017.
The ETV test has not been concluded but the results from the two periods give a preliminary indication of the effect of Active NS.
The testing and measuring methods are described in FORCE Technology report 116-20216.
As data from 2017, which was used in this report, is to be used in connection with an ETV test ending in mid-2018, the data and calculations have not been reviewed by anyone other than the report writer. Implementation of quality assurance has been planned in connection with final reporting on the ETV test. Data from 2016 has been quality assured.
